It is customary in laying rails, to provide a space between theoppositely disposedend faces of the lengths of the rails inline,sufficient to permit of the free longitudinal expans ion of therespective connected lengths of'the rails due to increase oftemperature, and thus to avoid deformation of the rails consequentderailment of the rolling sa k.

In practice, the spaces thus left between the ends o f the lengths ofthe rails permit of the fiexureof the ends of the rails'in' the passageover them of rolling stock, reason of the weight of the latter, wherebyas the wheels leave the end ofone rail, the

adjacent end of the other rail in line is d sposed' at a slightly higherle'vel, whereby undesirableshocksare imparted to the rolling.stOckQwhich result in inconvenience to passengers and disadvantages themaintename of the rolling stock and the permanent way. I

t' is one of the objects of the invention to avoid these disadvantagesby means that are equally applicable to railway rails and tramway rails.1

A d n to the nv a eny an nterm diate member is applied between adjacentlengths of rail in line, and serves to connect them, and thisintermediate member is provided with a part of a shape corresponding tothe head of the rails to extend over the space between the ends of therails in line, so that thus, on a wheel passing from the end of onerail, itbecomes supported on the in-. termediate member, and on leavingthe intermediate member, it then passes to and is supported by theadjacent rail.

The said intermediate member is'mounted and connected in such mannerthat the flexure of the adjacent rail ends cannot take placeindependently, and thus the adjacent rail ends under load are notmomentarily disposed at different levels, and thus resulting shocks areavoided. Moreover, the move ment of the wheels from rail to rail andover the jointing member, is smooth and does not cause vibration.

r The invention is illustrated by way of example, in the accompanyingdrawing applied to a connection between two adjacent lengths of arailway rail in line.

Figure 5 is a plan view showing the cornplet e d connection of the endsof two adjacent rails in line and showing the intermediate memberdisposed upon and between the opposite ends of the" lengths of rail,while Figure 4 is a side View opposite to that-at which the intermediatemember is applied.

As illustrated in the accompanying drawing, the rails land 2 disposed inline, have their heads partially removed to forinrecessed parts 13 and 4by which two inclined faces are thus formed extending from the innerside of the rail heads downwardly to the outer side, andby which alsoadjacent end faces are formed which are inclined out wa rdly fromtheinnervside" of the rail heads 7 to the outerside thereof, whereby theangle indieated at 5 in Figure 3 between theinclined end faces isobtuse, 1' I -The' intermediate -meinber, Figure 1, is provided with apart 7 which is complementary to the recesses formed in the heads of ithe adj acentlengths of rail that is to 'saythe intermediate member isprovidedwithan -inclined bottom face which is adapted te'lie upon theinclinedfaces ofthe recessed parts 3 and 4 and with inclinedend facesthat are adapted to lie in contact with the end faces of'the saidrecessed parts, so thatwhen the intermediate members is applied inposition, it completely fills the recesses, and its upper surface 8forms a continuation to the upper part of the normal section of the headof the connected rails, so that thus, on the intermediate member beingset into position, the part 7 forms, with the adjacent rail heads ofnormal section at 9 and 10, a substantially continuous rail head andsurface upon which the wheels of the rolling stock mayv roll, and inwhich, instead of, the usual butt jointing space 6 being exposed on thetop of the rail head, a joint 11, 12, 13 and 14 is formed that extendsfrom one side of the "rail to the other, in the manner indicated inFigure 3.

The intermediate member, Figure 1, in addition to the part 7 integrallyformed with it, is provided with a lower mounting plate 15 havingholes'16, 17, 18, 19 therein,

' by which it is adapted to be fixed by means of bolts 20, 21, 22, 23 tothe web of the rail" in position beneath the normal head thereof. Thismounting plate, at its lower edge, is applied against the feet 34, 35 ofthe respective adjacent rail lengths, in such manner; that the endsof'the lengths are not free in their movements of fiexture. If it besupposed that the rolling stock passes from left to right by referenceto Figure 3, the wheel which is supported upon the whole width 24 of therail head, by reason of the acute angle 25 and its opposite angle 26,gradually loses the support of the rail 1 and gradually acquires supportupon the part 7 of the intermediate member until the line 27 isattained, whence it gradually loses support from the part 7 of theintermediate member and radually acquires support upon the rail 2 yreason of theacute angle formed at 28 and the opposite acute angleformed at 29 i between the adjacent parts of the head section 7 of theintermediate part and the normal sectionof the head of the rail.

It will be understood that the superficial profile of the upper part ofthe intermediate member may correspond to the normal profile of the headof the adjacent rail sections in order to avoid irregularities, and inorder to ensure smooth running over the joint between the ends of therail lengths. It will thus be understood that the passage of rollingstock over the rail joints is imperceptible and without shock orvibration, since the usual transverse joint is replaced by a joint havina broken confi uration which a proaches the longitudinal axis of therail,

and which does not permit of the independentflexure of the connectedrail ends:

The intermediate member as hereinbefore described, is.mounted by meansof bolts 20, 21, 22, 23 in applying on the opposite side ofthe rail, anordinary fish plate 36 corresponding to the plate 15 and adapted, as isI the plate 15, to engage on the feet of the respective rails and therail heads, and the rails are provided with corresponding holes or slots80, 31, 32, 33 for the passage of these bolts.

I claim 2- A joint for rails comprising in combina-' inner side of therail head to the outer side thereof and to form a corresponding end faceto extend transversely and outwardly .from the inner side of therespective rail head to the outer side thereof, and an in termediatejoining member having a head part whose profile corresponds to that ofthe head of the said rail lengths and of a form adapted to fit withinthe cavity constituted of the oppositely disposed recessed parts formedin the heads of the rail ends, the said head part of the joining memberhaving inclined ends and an inclined under face and the said oiningmember being adapted to be secured to the adjacent ends of the raillengths whereby the rail head part of the saidjoining member ismaintained in position within the said cavity and in contact with theinclined faces thereof, substantially as hereinbefore described.
